How do I execute a list of piped and non-piped commands?

[folaht]

I'm trying to make a list of commands including piped commands and running them.
And I'm failing at that.
I've looked at multiple examples at this forum and stackoverflow of people doing piped commands and each one seems different, so I'm utterly confused.

These are the two main ones I'm looking at:

How to pipe commands in rust?

Pearl: Pipe two `Command` together

And other sample showing how to pipe to a child process's stdin from Rust itself: fn pipe_from_rust() -> Result<(), Error> { let mut child = std::process::Command::new("rg") .arg("toml") .stdin(std::process::Stdio::piped()) .stdout(std::process::Stdio::piped()) .spawn()?; // Ensures that the handle to `stdin` drops and closes, avoiding a deadlock. { let mut stdin: std::process::ChildStdin = child.stdin.take().unwrap(); writeln!(stdin,…

And this is what I've got so far:

In both examples my first issue seems to be that I've encased the process child
with an option type and it's telling me that a move has occured.

I usually fix such issues with cloning or adding a copy trait to a type that I made myself,
but this is a standard type, child or option, so I'm clueless on what to do about it.

Not sure it suits your specific needs, but I found duct to be helpful when I was struggling with setting up piping between processes.

This could be the solution that I need.
If duct can run commands, including piped commands just fine, I wouldn't need to bother reinventing the wheel.
